If I haven't mentioned it before, loading a new instance of 12.9.1 (scaled) with nothing going on seems to have some framerate problems. Scrolling through the browser, playlist, chael rack, and mixer just feels sluggish, as if the system is struggling to render the graphics. These framerate issues often disappear once the project gets a little more involved. I haven't found a definite threshold or cause for that yet, and I doubt any but the most snobbishly picky devs or users would even notice the dropped frames.

Again, loading 12.9.1 (scaled) as a VST from 12.5.1 (scaled) starts off beautifully smooth, with no drop in framerate.

Which reminds me; the 12.9.1 VSTi loaded with its toolbars slightly disheveled. Not sure if that was just a bug on my end or not. Thankfully its an easy fix -- just drag them back to normal.
